Herakleonas of Byzantium (626-641) was the Emperor of the Byzantine Empire from February to September 641, succeeding Constantine III of Byzantium and preceding Constans II of Byzantium.

Biography
Herakleonas was born in 626 to the House of Herakleidon, and he was a son of Heraclius. Herakleonas was the fourth son of Heraclius, but the first one that was eligible for the throne due to the lack of physical deformity. In February 641, following the death of his brother Constantine III of Byzantium, he was left as the sole emperor at the age of 15. Some believed that he murdered Constantine, so general Valentinus forced him to recognize his young nephew Constans II of Byzantium as co-emperor. However, Valentinus went on to spread rumors that Valentinus wanted to murder Constans, and a revolt occurred. Herakleonas' nose was cut off and he was banished, and he died at the age of 15. Constans succeeded him.
